Results: 30 of 30 patients reported a reduction in pain. Pre-operative visual analog reported pain was averaged 8.2 and decreased to an average of 1.3 after surgery. (p < .00) 27 of 30 patients were satisfied with the outcome of the surgery. 27 of 30 patients would proceed with the same procedure again. 26 of 30 patients would recommend it to a friend. Satisfaction was directly correlated with a decrease in visual analog pain scores. (r = -.43, p = .02) 29 thumbs adducted fully in the plane of the palm and opposed the fifth metacarpal head. Post-operative grip, oppositional pinch and appositional pinch strength were 97%, 93% and 85% of the contralateral hand respectively. The mean arthroplasty space was 1.5 mm in satisfied patients and 1.0 mm in dissatisfied patients with a significant correlation between dissatisfaction and lower post-operative arthroplasty space. (p = .018) Pre-operative QuickDASH outcome scores were obtained and 10 patients averaged 42. Post-operative QuickDASH scores were obtained in those 10 patients and averaged 23 while the average of all 30 patients was 19. (p = .03)
